How many muscles can you name in the human back. And how come there is no anatomy category? (kidding)

Um... I kind of slept through most of that class, but let's see if I can recall.... Um... there's Fred, and his best friend Malcolm up there near the top (I swear those two are inseparable).  Then there's John  (although he looks spindly, he's actually quite strong).  That's Sam there towards the middle (a rather twisted dude if you ask me).... and I believe that's penelope there by the tail (always bringing up the rear).
